Hi,everyone
After relax ,copy CONTCAR to POSCAR,and do static calculation,then there is a
error:
VERY BAD NEWS! internal error in subroutine SGRCON:
Found some non-integer element in rotation matrix 2
What's this problem and how to solve?
Thanks for your advice!

Maybe the space group after relaxation is almost changed. Try set SYMPREC or refine your atomic positions
according to the new space group.

please have a look if your relaxation gave a resonable result.
